I noticed another problem in Snake Eater.
The graphics looks super weird and I know for sure that's not how it supposed to look like.

If you look closely, there some form of "ghosting" around pretty much everything except the HUD elements.
It's like both Stereoscopic and a crap ton of bloom was applied.
I've looked at the Snake Eater entry in the PCSX2 wiki and adjusted the settings accordingly.
Yet it looks like this.
